Description

Technical Field

[0001] This invention relates to the technical field of steel pipe processing equipment, specifically to a saw blade positioning structure for steel pipe cutting equipment. Background Technology

[0002] Steel pipes are steel materials with a hollow cross-section, whose length is much greater than its diameter or circumference. They are classified according to their cross-sectional shape into round, square, rectangular, and irregularly shaped steel pipes; according to their material into carbon structural steel pipes, low-alloy structural steel pipes, alloy steel pipes, and composite steel pipes; according to their application into pipes for transportation, engineering structures, thermal equipment, petrochemical industry, machinery manufacturing, geological drilling, and high-pressure equipment; and according to their manufacturing process into seamless steel pipes and welded steel pipes. Seamless steel pipes are further divided into hot-rolled and cold-rolled types, while welded steel pipes are divided into straight-seam welded steel pipes and spiral-seam welded steel pipes.

[0003] In the actual processing of steel pipes, long steel pipes need to be cut into fixed lengths using cutting equipment. However, the saw blade structure on traditional steel pipe cutting equipment is simply fixed with nuts. During the high-speed operation of the saw blade, due to the relative force between the saw blade and the steel pipe, the saw blade will generate a certain resonance phenomenon, which will cause the nut used for positioning the saw blade to resonate as well. This can lead to the nut loosening and falling off, thus leaving certain safety hazards in the processing process. This invention proposes a saw blade positioning structure for steel pipe cutting equipment to solve the above problems. Summary of the Invention
